Movable door/window structure

Abstract

The invention relates to the field of movable door / window structures. A movable door / window structure comprises a door / window frame and casements, wherein rails are arranged in an upper frame and a lower frame of the door / window frame, and each casement is composed of a shaft edge mullion, a pin edge mullion, a top rail and a bottom rail. The upper ends of the shaft edge mullions of the casements are hinged to an upper sliding frame of an H-shaped frame, and the lower ends of the shaft edge mullions are hinged to a lower sliding frame of the H-shaped frame. The H-shaped frame comprises the upper sliding frame, the lower sliding frame and a stand column, and the stand column is respectively and fixedly connected with the upper sliding frame and the lower sliding frame. Sliding wheels mounted on the upper sliding frame are arranged in the rail of the upper frame, and sliding wheels mounted on the lower sliding frame are arranged in the rail of the lower frame. The sliding wheels comprise perpendicular sliding wheels and horizontal sliding wheels, the perpendicular sliding wheels are mounted at the end of the upper sliding frame and the end of the lower sliding frame, and the positions and the diameters of the horizontal sliding wheels are matched with slots of the rails of the upper frame and the lower frame of the door / window frame. The movable door / window structure meets the requirement that the casements can move left and right and can be pushed and pulled in an overhanging mode, and is stable and reliable when the casements are moved or pushed or pulled or folded.

Description

technical field [0001] The invention relates to the field of a movable door and window structure, in particular to a door and window made of metal, glass, plastic or other materials, which has the function of moving and pushing.

Problems solved by technology

However, since the doors and windows are connected by living hinges to the columns, when applied to medium and large doors and windows, due to the heavy weight of the doors and windows, the doors and windows cannot be stable and reliable when they are pushed and pulled from the outside, and the doors and windows can only be opened due to the use of living hinges. Push-pull overhang in one direction

The doors and windows connected by living hinges have little activity damping. In a windy environment, the doors and windows are easily blown by the wind and collide, destroying the doors and windows.

These greatly limit its application effect and its scope
